x86: Optimize load of const FP all bits set vectors
Check float_vector_all_ones_operand for vector floating-point modes to
optimize load of const floating-point all bits set vectors.

* config/i386/constraints.md (BC): Document for integer SSE
constant all bits set operand.
(BF): New constraint for const floating-point all bits set
vectors.
* config/i386/i386.c (standard_sse_constant_p): Likewise.
(standard_sse_constant_opcode): Likewise.
* config/i386/sse.md (sseconstm1): New mode attribute.
(mov<mode>_internal): Replace BC with <sseconstm1>.
